  • 6. Subject is willing and able to comply with scheduled visits, treatment plan, screening laboratory tests and other trial procedures.
  • 7. Subject must have a daily worst pain at the reference site score of at least 4 on an 11- point anchored scale at Screening (Visit 1).
  • 8. The subject has a performance status score of 0-2 (inclusive) as measured by the ECOG.
  • 9. Life expectancy =3 months from start of the study
  • 10. Creatinine Clearance =30 mL/min as calculated by the Cockcroft-Gault equation.
  • 11. Total white blood cell count >1500 per cubic millimeter; platelet count =50 x103 per cubic millimeter.
  • 12. If applicable, stable (initiated = one month prior to Screening) chemotherapy treatment, and no initiation of new chemotherapy regimen planned over course of the study.
  • 13. If applicable, radiotherapy or radiopharmaceutical treatment to the target lesion initiated =15 days prior to Screening, and no initiation of new therapy planned to target lesion over course of study.
  • 14. If applicable, stable bisphosphonate therapy (ie, initiated more than two months prior to Screening) and no new bisphonsponate therapy planned over course of study.
  • 15. Subject must have an average ‘Daily Worst Pain’ score of =4 at the reference site (as recorded in the daily diary) in the week preceding randomization (minimum 4 data points); and
  • 16. Subject must be treated with opioid therapy such that he/she takes a constant daily dose of opioid (SR or IR), with =4 doses IR opioid per day allowed as rescue medication in the week preceding randomization; and
  • 17. Subject must not be experiencing intolerable side effects from the total daily dose of opioids (eg, dose limiting side effects in the opinion of the patient and/or investigator).
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range
